Compositions for stabilizing chlorinated water to sunlight decomposition, and methods of preparation thereof - The invention includes a composition for stabilizing chlorinated water to sunlight decomposition, and methods of preparing compositions. The composition is a slurry composition of a monoalkali metal cyanurate, of low viscosity. Two methods of preparing the slurry are described, in which cyanuric acid or cyanuric acid wetcake is mixed with a monoalkali metal base. One method dry blends cyanuric acid or cyanuric acid wetcake with a monoalkali metal base. The invention also describes a method of preparing a dry, solid monoalkali metal cyanurate.

Microbiological Control in Aqueous Systems - Microbiological control is achieved by continuously and inexpensively dosing water in contact with biofilm, or that comes into contact with biofilm, using a highly effective biocide that provides very effective microbiocidal control of planktonic microorganisms and of biofilm species, even where the biofilm infestations have been in existence for long periods of time and thus have encased themselves in a substantial quantity of slimy defensive polysaccharide layers or films. In addition, the biocide used makes possible significant reduction in copper and/or iron surfaces in contact with the water as compared to N,N′-bromochloro-5,5-dimethyl hydantoin. Still other advantages are made possible by the described technology.

Antimicrobial ice compositions, methods of preparation, and methods of use - The invention includes antimicrobial ice compositions (also called frozen antimicrobial compositions), methods of preparing the compositions, and methods of using the compositions. The frozen composition includes a peroxycarboxylic acid and hydrogen peroxide. The compositions are used to prevent spoilage and microbial contamination of perishable foods, such as fresh fruit, fresh vegetables, meat, poultry, fish, seafood, and shellfish. The compositions may also be used in the processing of sausage or luncheon meat to prevent spoilage and contamination.

Methods and compositions for the reduction of pathogenic microorganisms from meat and poultry carcasses, trim and offal - The invention includes a method of preparing hypochlorite-activated solutions of hypobromous acid and/or hypobromite ion. The method includes the steps of mixing a solution of a source of bromide ion with a solution of a source of hypochlorite ion to activate the bromide ion, allowing sufficient time to maximize the activation of the bromide ion, and storing the solution before use. The invention also includes a method of using the solution to wash meat and poultry carcasses, trim, and offal to reduce pathogenic microorganisms. The solutions may also be used to reduce pathogenic microorganisms in industrial cooling water and on food contact hard surfaces and equipment. The solutions may be stored for up to about three hours before use and are stable for that period of time.

Methods and compositions for the reduction of pathogenic microorganisms from meat and poultry carcasses, trim and offal - The invention includes a method of preparing hypobromous acid by mixing an aqueous solution of hydrogen bromide and a source of hypochlorite with water. The invention also includes a method of using the hypobromous acid prepared by this method to wash animal carcasses, trim, and offal to reduce microorganisms, in particular, human pathogenic bacteria, on and in the carcasses, trim, or offal. Compositions of hypobromous acid are also described. The hypobromous acid of the invention may also be used to reduce fat, oil, and grease build-up on equipment and hard surfaces used in the processing of animal carcasses, trim, and offal.

Methods of using peracetic acid to treat poultry in a chill tank during processing to increase weight - Methods for treating poultry during processing for increasing the weight of the poultry are disclosed. The methods may be performed in a chill tank or other reservoir and utilize either equilibrium peracetic acid or non-equilibrium peracetic acid. The non-equilibrium peracetic acid may be prepared from hydrogen peroxide and a liquid acetyl precursor, such as triacetin. The methods comprise contacting a poultry carcass with peracetic acid-containing water at a pH of about 6 to about 9. The methods result in an increase in the weight of the processed products and an increase in a processing plant's percent yield of the processed products.

Methods and compositions for the generation of peracetic acid on site at the point-of-use - Methods and compositions for the generation of a peroxyacetic acid sanitizer in proximity to the point-of-use are disclosed. These methods comprise introducing a hydrogen peroxide-acetyl precursor solution to water, mixing, and then adding an aqueous source of a alkali metal or earth alkali metal hydroxide. Triacetin is a preferred acetyl precursor and is converted rapidly and with a high conversion rate into peracetic acid. These methods produce solutions with a high level of peracetic acid. Methods for preparing the hydrogen peroxide-acetyl precursor solution are also provided. Also disclosed are solid compositions comprising a liquid acetyl precursor, a water-soluble source of hydrogen peroxide, and a water-soluble source of alkalinity. The solid composition is a freely-flowable solid that is used as a bleaching agent and a stain remover for the treatment of articles such as fabrics, dentures, textile garments, and equipment used in the food and beverage industry.
